Low cost monochrome 7 segment LCD display
Dug up an old prototype of a low cost monochrome 7 segment LCD display + DS18B20 temperature sensor + Atmega328 + RFM69 433Mhz transceiver project. 30uA sleep current. e-paper is still relatively more expensive alternative. #IoT
49mA with display off and maximum wifi power savings
49mA with display off and maximum wifi power savings + DFS enabled while maintaining WiFi and 433Mhz connections to low power battery sensors Note that this is at 5.12V or roughly 80mA on 3.3V; CPU speed varied between 160 and 80Mhz as needed

ESP32 based thermostat controller/gateway project with TFT
It's close to a year since I started working on my ESP32 based thermostat controller/gateway project with TFT display. It now has 120K+ lines of code (components included), work done entirely at nights/weekends. What's the longest you have worked on a passion project? #IoT https://x.com/mharizanov/status/1027868368500666368
Experimenting with a 3.5″ TFT
Testing the TFT32 ESP32 project on a 3.5″ ILI9488 480×320 resistive touch TFT – mostly a matter of adapting the display drivers.

Pushing an ILI9341 TFT to its limits with 60MHz DMA-enabled
Pushing an ILI9341 TFT to its limits with 60MHz DMA-enabled SPI on #ESP32 Correction: SPI can only run on 80/n frequencies [n between 1 and 8], so 8MHz, 8.89MHz, 10MHz, 11.43MHz, 16MHz, 20MHz, 26.67MHz, 40MHz, 80MHz . Setting SPI clock to 60MHz actually meant it got mapped to 40MHz, anything>60MHz meant setting to 80MHz. That…
